AI Technical Summary
The existing automotive swing arm painting equipment has the problem of low manual efficiency and easy to collide and lack of paint after spraying. The robot sprays evenly but needs to be equipped with a suspension conveyor. Traditional suspension conveyors can only be conveyed in an array, and the speed cannot be too fast, otherwise there will be problems such as swing arms shaking, colliding, and paint defects.
A paint spraying device for the production of automobile swing arm was designed, using pull-down tracks to control the stable movement of the suspension frame, and controlling the tension of the suspension frame through a spring to ensure smooth movement and avoid suffocation caused by distance changes.
